[X] This issue only relates to a single bug. I will open new issues for any other problems.

Describe the bug

I have a FialeDialog (doesn't matter if created with NewFileOpen or NewFileSave). When I navigate to the /dev/ directory on my Debain Linux and scroll down (doesn't matter if I use the scrollwheel of my mouse or the handlebar at the right side) the application freezes forever once I reach the row with the files entries mapper, media0, mem, and net. The row after that would have contained the entries null, nvram, port and ppp, the row after that psaux, ptmx, pts and random.

How to reproduce

Run go run fyne.io/fyne/v2/cmd/fyne_demo@v2.4.4, go to "Dialogs", click "File Save", go to /dev and scroll down until the app freezes.

Screenshots

This is where it froze:

Is the CPU usage high, or low? This could be some sort of tight loop or it could be a deadlock. If it is the former a CPU profile would help. If it's the latter can you please provide a debug stack trace so we can see what locked up?

Thanks for the quick response. CPU usage is not high. How do I get a debug stack trace?

I have obtained a backtrace with the delve debugger. Is this what you were looking for?
